Answer:
A. 190 Teenagers
B. 200 Teenagers
C. A situation where we can have percentage greater than 100 % is found during increase in growth of population
Step-by-step explanation:
Part A.
Mike surveyed 250 teenagers to find out their favorite food. He found that 76% of the teenagers surveyed like burgers. Part How many teenagers surveyed like burgers?
We were told from the question, 76% of the teenagers surveyed loved burgers.
Total number of teenagers = 250
Therefore, the number of teenagers surveyed that loved burgers =
76/100 × 250
= 190 teenagers
Part B: In another survey, Jane found that 25% of the total number of teenagers surveyed like sandwiches. If 50 teenagers like sandwiches, what is the total number of teenagers that Jane surveyed?
Let the total number of teenagers surveyed be represented by x
Therefore,
25% of x = 50 teenagers
25/100 × x = 50
25x/100 = 50
Cross Multiply
25x = 100 × 50
25x = 5000
x = 5000/25
x = 200
Therefore, 200 teenagers were surveyed
Part C: Give an example of a situation in which a percentage is greater than 100%. (2 points)
A situation where we can have percentage greater than 100 % is found during increase in growth of population

Answer: The slope is 2/3, y=2/3x+1
Step-by-step explanation: The 2 points, (3,3) and (6,5), use the method y2-y/x2-x1. Then you find the slope that way, then use point slope form for the slope intercept form: y-y1=m(x-x1), then substitute and solve to get y=2/3x+1

Solve the literal equation for a y=x(ab/a-b)
Answer:
a = (b + c)/(bx - 1)
Step-by-step explanation:
Given
x= (a+b+c)/(ab)
Solving for a
x = (a + b+ c)/(ab)
abx = a + b+ c
abx - a = b + c
a(bx - 1) = b + c
a = (b + c)/(bx - 1)

m is the slope, and we know that each time they need to drop $0.10 so that is our slope. For the b we just need to get $0.10 times 260 cards that need to sell and add 5 and we get 31. So, the equation is p= (-0.10)x + 31.

Step-by-step explanation:
9v
The polynomial function for the volume V of the tray in terms of x will be;
⇒ 4x³ - 30x² + 54x
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
Lucy cuts 4 squares with side length x inch from the corners of a 6 inch by 9 inch cardboard rectangle.
She folds the remaining cardboard to make a tray that is x inch high
Now,
By the give condition we get;
Length of tray = 9 - 2x
Width of tray = 6 - 2x
Height of tray = x
So., The volume of the tray is expressed as;
Volume = x (9 - 2x) (6 - 2x)
= x (54 - 18x - 12x + 4x²)
= x (54 - 30x + 4x²)
= 4x³ - 30x² + 54x
Thus, The polynomial function for the volume V of the tray in terms of x will be;
⇒ 4x³ - 30x² + 54x

Step-by-step explanation:
A carton has a length of fraction 2 and 2 over 3 feet, width of fraction 1 and 1 over 8 feet, and height of fraction 1 and 1 over 5 feet. What is the volume of the carton?
fraction 3 and 3 over 5 cubic feet
fraction 4 and 1 over 5 cubic feet
fraction 5 and 2 over 5 cubic feet
fraction 7 and 1 over 5 cubic feet
Given:
Length of a carton = [tex]2\dfrac{2}{3}[/tex] feet
Width of a carton = [tex]1\dfrac{1}{8}[/tex] feet
Height of a carton = [tex]1\dfrac{1}{5}[/tex] feet
To find:
The volume of the carton.
Solution:
We know that, volume of the carton is
[tex]V=length\times width \times height[/tex]
Putting the values, we get
[tex]V=2\dfrac{2}{3}\times 1\dfrac{1}{8} \times 1\dfrac{1}{5}[/tex]
[tex]V=\dfrac{(2\times 3)+2}{3}\times \dfrac{(1\times 8)+1}{8} \times \dfrac{(1\times 5)+1}{5}[/tex]
[tex]V=\dfrac{8}{3}\times \dfrac{9}{8} \times \dfrac{6}{5}[/tex]
Taking LCM, we get
[tex]V=\dfrac{18}{5}[/tex]
[tex]V=3\dfrac{3}{5}[/tex]
So, the volume is [tex]3\dfrac{3}{5}[/tex] cubic feet.
Therefore, the correct option is A.
Jana uses 20 cards to play a memory game the cards are either animal cards or fruit cards. The ratio of animal cards to fruit cards is 2:3 How many if the 20 cards are animal cards? Of the fruit cards, 1/3 have bananas on them. How many cards have bananas on them. Show or explain your work.
Given that,
Total no of cards = 20
The ratio of animal cards to fruit cards is 2:3
No of animal cards = 20
Solution,
Let there are 2x animal cards and 3x fruit cards. ATQ,
2x+3x = 20
5x = 20
x = 4
Animal cards = 2x
= 2(4)
= 8
Fruit cards = 3x
= 3(4)
= 12
It is also mentioned that, of the cards, 1/3 have bananas on them. It means,
[tex]B=\dfrac{1}{3}\times 12\\\\=4[/tex]
Hence, 4 cards have bananas on them.

Which number can each term of the equation be multiplied by to eliminate the decimals before solving?
–m + 0.02 + 2.1m = –1.45 – 4.81m
0.01
Answer:
Multiply by 100
Step-by-step explanation:
The equation is given as:
-m + 0.02 + 2.1m = -1.45 - 4.81m
To eliminate the decimals from all the terms, we must multiply by a number that make all the coefficients integers.
The decimal coefficients and independent terms are
0.02, 2.1, 1.45, 4.81
Note the maximum number of decimals found in all of them is 2. Thus, multiplying by 100 all the decimals will vanish as follows:
100(-m + 0.02 + 2.1m) = 100(-1.45 - 4.81m)
-100m + 2 + 210m = -145 - 481m
Now all terms have integer coefficients as required.
Answer: Multiply by 100

Solve the equation: 5 + 2(3 + 2x) = x + 3(x + 1)
Answer:
No solutions
Step-by-step explanation:
In this question, you would be solving for x.
Solve:
5 + 2(3 + 2x) = x + 3(x + 1)
Use the distributive property.
5 + 6 + 4x = x + 3x + 3
Combine like terms.
11 + 4x = 4x + 3
Subtract 4x from both sides.
11 = 3
Since we don't have an "x value", there are no solutions.
"No solutions" would be your answer.

landon elliot fumigates rooms and charges $21.95 per room on monday he fumigated 3 rooms in one house 2 in another and 4 in a third
The total charges are $197.55.
According to the statement
We have to find that the total charges.
So, For this purpose, we know that the
A equation is an algebraic equation of the shape y=mx+b. involving only a continuing and a first-order (linear) term, where m is that the slope and b is that the y-intercept.
From the given information:
He fumigated 3 rooms in one house, 2 in another, and 4 in an exceedingly third.
Then
Landon Elliott takes charges to fumigate each room = $21.95
He fumigated rooms on Monday = 3 + 2 + 4 = 9 rooms
His total charges = 21.95 × 9
His total charges= $197.55.
So, The total charges are $197.55.
